Executive Summary

The peer-to-peer content distribution systems are to register for a long term presence in a network and to publish its own data to that network. These requirements can be done by having some set of indexing and routing techniques. For this solution, a sequence of approaches has been already proposed by the existing researchers. But these approaches are not flexible for these systems and too complex. In the unstructured P2P system it uses to retrieve the data if it matches. Also, certain limitations are obtained. In order to solve this problem, the authors propose an approach of continuous query in unstructured overlay network with consistency maintenance. In peer-to-peer, consistency maintenance is widely used techniques for high system performance.
